Self-drilling screws, often referred to as Tek screws, are equipped with a drill bit-like tip that enables them to drill through metal and other hard materials. These screws are typically made from high-strength materials such as carbon steel or stainless steel, which grant them exceptional durability and resistance to corrosion. Self-drilling screws come in various sizes and lengths, suitable for different applications, from roofing and siding to metal framing and vehicle construction.

The primary advantage of self-drilling anchors lies in their efficiency. Traditional anchor installation methods often require multiple steps, including drilling, cleaning the hole, and inserting the anchor. In contrast, self-drilling anchors combine these functions into one, reducing time, labor, and overall project costs. This makes them particularly advantageous for projects where time is of the essence or where access to drilling equipment is limited.

The hallmark of self-drilling screws is their ability to create their own pilot holes, negating the need for pre-drilling, which can save significant time and effort during installation. The 13mm self-drilling screw is typically constructed from high-strength steel, ensuring durability and reliability. These screws often feature a sharp, drill-point tip which enables them to penetrate various materials quickly and efficiently. Coupled with a robust thread design, they provide excellent holding power, making them ideal for fastening metal, wood, and other materials.
